Images disappearing, chosen font keeps changing, sections turn to hidden.

Hi!
Have a site with enfold for a client of mine. Lately the theme has caused me serious problems, or at least I suspect it’s the theme. Every other day most of the images are not visible besides backend. If I open a page in enfold and simply save it again, the images turn up again. I have to do this with every page. Also, the font keeps changing back to default, although it says something else in the theme. För example; I have Open Sans, very thin and large in the settings. This worked before, but now the default versions are what you see when visiting the site, Enfold doesn’t seem to see my settings. A third issue is that some section turn to “Hidden” without my action. It says “click to view” This isn’t either anything I’ve done. That doesn’t really effect the appearance of the site, but it’s a drag not seeing the content as it’s intended backend. Some sections doesn’t either recognize the width I’ve set for it. If the block is 50%, it appears full width. I suspect these issues are related and that something is seriously wrong with the site/theme/installation or something. My client is loosing their patrons with it so I gently need help to solv these issues. I’m talking asap. Hopefully you guys can help out in this. The site has been up and running without a problem for over 3 years before this.
